When the programmer opens the plug-in

Chapter 65 Online Emergency Issues

After Cheng Wen imagined it this way, the Ruyi smart screen provided by the system did not change accordingly.

Also, the screen is just a screen, and the content can only come from other places.

Just like some VR devices now, most of them have to be connected to mobile phones or computers.

There are also some with their own internal operating system, which can install software without resorting to mobile phones and computers.

But this screen is different, it is not produced by any manufacturer, and there should be no operating system inside.

Seeing that the screen in front of him could be divided into many, Cheng Wen also divided a screen into his chat software.

But after a while, Cheng Wen decided to turn off the screen that was assigned to the chat software, because it was a waste of time to watch chats and water groups.

If you have to read information at work, that’s okay, but now he is alone at home, there is no need to stare at it, and it can reduce some interference, so reduce it. He can't be distracted by chat software.

Cheng Wen was still a little puzzled, he didn't know if this screen could be seen by others.

But this is easy to verify. Cheng Wen returned to the real world, took his mobile phone, and took some pictures of himself. Just look at the mobile phone.

The result was exactly as he thought. This time, other people could not see it, which made him feel relieved. If such a productive thing can only be used in the system space, it will be a great regret. Now it’s all right. , he can safely use it in bold real life.

Using virtual screens for learning is the primary productivity.

After Cheng Wen studied in this way for several hours, the time came to 12 o'clock in the evening.

Seeing that it was getting late, Cheng Wen went to bed, and at the same time thought to himself, "We can't do this anymore, we must strive to go to bed early and wake up early."

The next day was a very scorching sun day, uncomfortably hot.

================
Cheng Wen and their back-end development classmates are two php programmers.

Nowadays, there are still many people who use PHP to develop web sites.

But Ali is different, Ali is all based on java, and now some companies are starting to use go, go is a development language, just like c and c++, it is a language developed by google company, it has some characteristics Known for its performance, it is called the C language of the Internet.

Now there are many people engaged in php development who have turned to go language development.

Of course, the two back-end development students in Cheng Wen's team did not switch to Go, they still use PHP, but they will also learn some new things after work, and they actually know some Go.

The two of them had been colleagues in another company long before they came to this company, so they had a very good personal relationship.

On this Sunday, the two of them made an appointment with two other friends, and the four of them decided to play a game together.

This game is quite popular, called Escape Room.

In the afternoon, a few of them made an appointment, and one of them would drive, and the other would take a car. The four of them went to play this game together.

When they got there, they realized that they had to turn in their mobile phones when they went to play here. They didn't understand why, so they asked the staff.

The staff explained to them that this is because they are afraid that they will use their mobile phones to take pictures of some internal details and do some strategies.

They also expressed their understanding. They chose a one-hour game, and after thinking about it, there was no problem for an hour, so they handed over their phones.

But things are often such a coincidence that within 10 minutes after they entered, something went wrong with the product.

There are problems on all platforms, including mobile phones, computers and web pages.

Yao Shao is in the group @back-end development and front-end, let them quickly look at this problem together, and quickly solve this problem.

After 1 minute, the front-end students had feedback, and they said they knew the problem and were watching it.

Cheng Wen also saw the news at the time, and his mobile phone's WeChat was always online.

When the front-end students looked at this question, it was a long time before the back-end students responded.

After a few minutes, Yao Shao asked someone to call them, but the strange thing was that the call got through but no one answered.

[Feng Le, please help me to see if you can find out where the problem is not]

Yao Shao said in the group.

Feng Le is a back-end engineer, but he is engaged in C++, and his main job is to study some very low-level things.

I don't have much contact with this, but since the other two people can't be contacted, I can only find him.

【OK】

Before replying this sentence, Feng Le had been paying attention to this matter, but he didn't talk in the group.

When Cheng Wen saw this question, he was not idle.

After all, he and this product are now in a bonded relationship, one prospers and the other loses. It is not enough to move a small bench and sit there to eat melons, and shout 666 from time to time.

But no one else thought of Cheng Wen. After all, it was not very common for a test to be called to look at the problem suddenly.

Their products had similar problems before, so the front end naturally thought of the previous experience.

But after looking at the prompt on the web page, there is no cross-domain error reported, so it is not a cross-domain problem.

The software they made is a remote conference, and it can also be viewed as a live broadcast. In fact, the technology is the same.

Just slightly different in usage.

In remote meetings, multiple people can speak at the same time, or multiple people can video at the same time.

The function of live broadcast is relatively simple. Only one person can upload video or audio stream, and everyone else is watching.

In both modes, other people can send texts, which is the same place.

The problem this time is that during the meeting, others cannot see the picture or hear the sound. This problem exists in both modes.

The front-end students read some information from the browser, and the browser they use is called chrome.

This is a free browser developed by Google, and it is used by a large number of people now.

A very useful feature of this browser is that it provides some developer tools.

Later, other browsers also borrowed this idea, such as the previous Firefox browser, which used a plug-in to realize this function, and later it also realized this function in its own browser.

As the name implies, this function is prepared for developers. Developers can see a lot of network requests through this browser, as well as some cookies and downloaded resources.

However, the front end did not find the reason in the browser, and found any errors, and everything looked very normal.
